Description
This works only with supervised devices (MDM) and allows Apple Game Center to be disabled. The rationale is Game Center is using Apple ID and will share data on AppleID-based services; therefore, Game Center must be disabled. This setting also prohibits the functionality of adding friends to Game Center.
ℹ️ Check
Verify the macOS system is configured to disable iCloud Game Center with the following command: /usr/bin/osascript -l JavaScript << EOS $.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\ .objectForKey('allowGameCenter').js EOS If the result is not "false", this is a finding.
✔️ Fix
Configure the macOS system to disable iCloud Game Center by installing the "com.apple.applicationaccess" configuration profile.
